DTC P2563 Volkswagen, Audi, Skoda and SEAT cars log when the small actuator that moves the turbo’s vanes (or its wastegate on a petrol) isn’t ending up where the engine computer asked. On most VAG diesels that’s a tired rubber diaphragm inside that actuator or a vacuum leak, and VW’s own bulletin says fit a new actuator, not a turbo: £220 to £390 fitted in the quotes I found. On the TSI petrols it’s the electric wastegate actuator. You can drive it for a few days. The test that settles it is a hand vacuum pump on the actuator. Your tool may show it as P256300, P2563 00 or 18995/P2563/009571.
Can You Drive With P2563?
Yes, for a few days, and on a diesel the clock runs faster than you’d think.
On a diesel the engine warning light stays on with the code, and a regeneration, the burn-off that keeps the DPF clear, won’t complete while that light is on for any fault. The soot builds: one owner had the DPF light five days after the code. Book it in at the first flash of the glow plug warning light, not after the DPF light.
On a TSI petrol the EPC light comes on and the car drops into limp mode in the reported cases. It’ll get you to a garage; don’t push it there.
Stop if P0299 (underboost) or P0234 (overboost) joins it with smoke, a whistle under load or a car that won’t pull up a hill.
What P2563 (P256300) Means on a VW, Audi, Skoda or SEAT
The ECU, the engine computer, tells the turbo actuator where to put the vanes on a diesel, or the wastegate on a petrol, and a sensor inside the actuator reports back where they ended up. P2563 is the ECU saying the two didn’t match. It isn’t a wiring code: the circuit works, the position is wrong, which is what a vacuum leak or a soft diaphragm produces. VW’s wording is “position sensor for boost pressure controller has an implausible signal”; the “sensor A” of the generic text is turbo 1.
The codes stored with it narrow it down. P2564 or P2565 means the wiring or the sensor itself. P00AF means the actuator didn’t move at all. A P0299 code means boost was lost as a result, and P2263 (boost system performance) can sit beside it on a TSI.
Where the P2563 Sensor Is and Which Actuator You Have
The sensor is built into the actuator, which sits on the turbo, behind the engine on the transverse cars. Three designs exist, and the part, the test and the bill depend on which is on yours.
Vacuum Actuator With a Position Sensor
A round metal can with a vacuum hose into the top and a small plug on the side. It’s on nearly every 1.6 and 2.0 TDI from 2008 on (the list is below). Two turbo makers fit these engines and their units differ, so the turbo’s part number decides which you buy.
Electric Actuator
A black box with a multi-pin plug and no vacuum hose; a motor moves the vanes. It’s on some vans and the 3.0 TDI V6 (list below). What fails is the motor and gears inside it, vanes seized so it can’t reach its end stop, or the wiring. A new unit needs a basic setting, the tool-guided routine that teaches the computer its end stops.
Electric Wastegate Actuator on the TSI
On the petrol turbos an electric actuator with its own sensor pushes a rod to the wastegate lever. The 1.4 and 1.5 TSI set the code from their own electric actuators, so the lever test and adaptation below apply; the 1.5’s rattling actuator rod is that part wearing (see 1.5 TSI problems and 1.4 TSI engine problems).
Which Diesels Have Which Actuator
Vacuum unit with sensor: nearly every transverse 1.6 and 2.0 TDI from 2008 on. Golf Mk6 and Mk7, Jetta, Polo, Passat B6 to B8 and CC, Tiguan, Touran, Caddy, Scirocco, Sharan, T6 Transporter and Crafter single turbos; Octavia Mk2 and Mk3, Fabia, Roomster, Rapid, Superb, Yeti, Karoq, Kodiaq; Leon Mk2 and Mk3, Ibiza, Altea, Toledo, Alhambra, Ateca; A1, A3 8P and 8V, Q2, Q3.
Electric actuator: T5.1 Transporter, the big turbo on the 2011 to 2016 Crafter and Amarok bi-turbos, and the 3.0 TDI V6 in the A4, A5, A6, Q5, Q7 and Touareg.
Longitudinal A4 B8, A5 and Q5 2.0 TDI: same code and the same sensor name. Find the actuator with step 2 and follow its route; I haven’t verified the part, so order by VIN.
Which Petrols Have the Electric Wastegate Actuator
Golf GTI and R, Jetta GLI, Passat and Tiguan 1.8 and 2.0 TSI, Beetle 1.8T; Octavia vRS and Superb 2.0 TSI; Leon Cupra; A3, S3, TT and TTS; the A4, A5 and Q5 2.0 TFSI from 2016; every 1.4 and 1.5 TSI.
P2563 Causes on the 2.0 TDI, 1.6 TDI and TSI, in Order
Diesel With the Vacuum Actuator
A leaking actuator diaphragm. VW’s own bulletin names it and tells the dealer to replace the diaphragm with its sensor, not the turbo. It starts intermittent and ends in P0299 and limp mode.
A kinked, split or leaking vacuum hose, or a weak N75, the valve that feeds the actuator its vacuum. The bulletin’s first check. Hoses near the exhaust harden and crack.
A leaking crankcase pressure control valve on the 1.6 TDI. On the 2009 to 2015 1.6 TDI the valve in the cam cover fails and bleeds away the actuator’s vacuum. A new cam cover fixes it.
Vanes or linkage binding. Soot or corrosion stops the vanes following the actuator. The lever test finds it, and it’s the one cause that ends in a turbo.
A rotated turbine housing or a broken clamp stud. Bulletin cause number two, and it means a turbo.
Petrol With the Electric Wastegate Actuator
The actuator itself. The motor, the plastic gears or the sensor wear out in the heat.
A seized or corroded wastegate arm. The actuator is fine; the lever it pushes isn’t. A run of these on 2015 to 2020 1.8 and 2.0 TSI cars traced to a corroding pivot shaft: dealers fit a complete turbo, specialists free the shaft with heat or fit a stainless one.
A rod set wrong, or no adaptation, after earlier work. The code returns until the adaptation passes.
Heat-damaged wiring. The loom runs beside the exhaust manifold.
What Are the Symptoms of P2563?
On a VW, Audi, Skoda or SEAT diesel, P2563 shows up as a flashing glow plug light with “Engine fault: workshop” on the dash and full power at first; owners then report limp mode with P0299 and a DPF light within days. On a TSI petrol it’s the EPC light and limp mode.
Diesel With a Vacuum Actuator
- Flashing glow plug light. The coil symbol flashes for a minute or so, goes out, and comes back on a later drive. A glow plug fault stays on instead.
- “Engine fault: workshop” message. In the cluster while the light flashes.
- Full power at first. In the reported cases the car drove normally for days.
- Little pull low down, then limp mode with P0299. One owner describes “almost zero pull until 3,500 rpm” before limp mode.
- DPF light within days. Regeneration doesn’t complete while the engine light is on.
- Not from P2563: misfire, rough idle or smoke. Any of those means a second fault.
TSI Petrol With the Electric Wastegate Actuator
- EPC light with the engine light. One reported case had both, with P2565 stored alongside.
- Limp mode or no boost. Slow pulling away and hesitation under throttle.
Diesel With an Electric Actuator
- Reduced power with the glow plug light flashing. P00AF may be stored with P2563 if the actuator stopped moving.
How to Diagnose P2563 Step by Step
Steps 1, 2, 5 and 6 apply to every engine. Steps 3 and 4 are for the vacuum unit; step 7 is for the TSI and the other electric wastegate cars. An electric-actuator diesel goes 1, 2, 5, 6 and then straight to the basic setting in the fix.
Not doing this yourself? Steps 1 and 2 are still yours; then take the car in and ask for steps 3 to 5 by name. The garage’s answers to those three are what you’ll check in the DIY or Garage section below.
1. Read Every Code and the Freeze Frame
A generic scanner gives you P2563 alone. OBDeleven or VCDS gives you the six-digit form, the codes stored with it and the freeze frame, the readings saved at the moment the code set, including the sensor voltage. The Vgate iCar Pro with Car Scanner reads the generic code and live boost; the actuator values need OBDeleven or VCDS.
2. Find the Actuator
Behind the engine on the transverse diesels, reached from above with the air box and turbo inlet pipe off. The three designs are described above.
3. Check the Vacuum Supply
Trace every hose from the vacuum pump through the N75 to the actuator for splits, kinks and hoses pushed on but not sealing. Pull the hose off the actuator and suck on its stub: a diaphragm that won’t hold even that is finished. On a 1.6 TDI, put the hand pump on the cam cover’s vacuum port; it must build and hold vacuum. Output-test the N75 and listen for the click.
4. The Hand-Pump Test With Live Data
Engine off, ignition on, sensor voltage on screen (VCDS measuring block 120, field 4, or the charge pressure actuator position in OBDeleven live data). Healthy readings: about 3.5 V with no vacuum; pump to 17 inHg (about 575 mbar) and it should drop to around 0.7 V and hold; about 0.7 V again at idle. VW’s own test is simpler: pump to about 600 mbar and see if it holds. Vacuum that won’t hold is the diaphragm. Voltage that won’t move is seized vanes or a dead sensor.
5. Check the Lever Moves
Unclip the actuator rod and swing the lever by hand through its full travel. It should move freely with light resistance. Gritty, stiff or stuck means the vanes or the wastegate pivot, and no actuator will fix that.
6. Check the Plug and the Loom
Unplug the actuator and look for green or black pins, melted insulation where the loom passes the exhaust, and a connector not fully latched. A wiring fault normally stores P2564 or P2565 too, so if either is there, the loom comes first.
7. On a TSI, Read the Actuator Value and Run the Adaptation
Key on, engine off. Read the actuator value: “Charge air pressure actuator: acknowledgment” in VCDS (IDE00396), “Charge pressure actuator: acknowledgment” in OBDeleven live data. It should read 3.5 to 3.9 V. If it does, run the adaptation: basic setting IDE04304 in VCDS, “First adaptation of charge pressure actuator” in OBDeleven. Grinding, clicking or a failed test means the actuator. A pass, then the code back on the road, means the wastegate arm is binding.
How to Fix Code P2563 Step by Step
Do only the step the diagnosis pointed you to, then clear the code and drive it. Vacuum unit: steps 1, 3, 4 and 8. Electric diesel actuator: 2, 5 and 8. TSI and electric wastegate: 2, 6 and 8. Step 7 only when the lever failed step 5 of the diagnosis.
If a garage is doing it, the only line that matters to you is in step 4: the new unit has to be set with a gauge and live data, then adapted. A rod set by eye brings the code back.
1. Repair the Vacuum Side
Replace any split, kinked or loose hose between the vacuum pump, the N75 and the actuator, with proper clips. Replace the N75 only if its output test failed, and check you’re on the right plug: on some cars it also fits the crankcase breather heater next to it. On a 1.6 TDI whose cam cover wouldn’t hold vacuum, fit a new cover with its valve and gasket.
2. Clean or Repair the Plug and Loom
Clean corroded pins with contact cleaner, add dielectric grease, latch the connector and repair any chafed or melted loom. This is the fix when P2564 or P2565 is stored with P2563.
3. Replace a Vacuum Actuator
Buy the unit by the turbo’s part number, not the engine; the two turbo makers’ units differ (part numbers at the end of this section). The job is done from above: air box, intake pipe and inlet elbow off, rod unclipped, unit swapped, hose and plug on.
4. Set the Rod and Run the Basic Settings
With live data on screen: loosen the lower rod nut, pull vacuum so the rod sits fully home, set the voltage with the upper nut (owners quote 0.4 V at full travel), tighten the lower nut, release the vacuum and check the reading sits in the released range, then lock the nut with thread adhesive and the safety pin. The nuts need a cut-away socket and a thin spanner; a £23 turbo adjustment kit covers both. Clear the codes and run the charge pressure controller basic settings.
5. Replace an Electric Actuator and Run the Basic Setting
Fit the new unit, connect the plug, and run the basic setting with VCDS, ODIS or OBDeleven PRO before you drive it. If it fails or you hear grinding, the vanes are seized: step 7.
6. Replace a TSI Wastegate Actuator
Fit the actuator and connect the rod. Ignition on, engine off, loosen the jam nut and turn the rod until the actuator value reads 3.5 to 3.9 V, tighten the nut, then run the adaptation and wait for “Finished correctly”. One workshop case passed at 3.51 and failed at 3.49, so go by the reading, never by eye. A code straight after fitting is normal until the adaptation has run.
7. Replace the Turbo
Only when the lever is seized, the housing has rotated or the vanes are damaged. VW supplies some turbos only complete, which is why a dealer quotes a turbo when the actuator is all that’s needed; specialists sell the actuator alone. On a TSI with a seized wastegate shaft, ask about a stainless-shaft rebuild before you buy a complete turbo. A new turbo’s actuator still has to be set or adapted.
8. Confirm the Fix
Clear the code, drive a mixed route with a couple of full-throttle pulls in third, then read it again: actual position following specified, nothing pending after two drive cycles. If the DPF light came on, do a long run above 2,000 rpm or have a forced regeneration done, then check the soot load; see what a DPF regeneration needs.
Part numbers, to check against your VIN: 2.0 TDI vacuum unit for the KKK turbo 03L198716A (also listed as 03L198716L); TSI wastegate actuator 06K145614G (GTI) and 06K145725T (Golf R); longitudinal A4, A5 and Q5 2.0 TFSI 06L145612E/F; 3.0 TDI electric unit Hella 6NW010430 or Garrett 823699; turbo adjustment kit Laser 7070 or Sealey VS2032.
P2563: DIY or Garage?
Do it yourself: a hose, a clip, a plug, the loom repair and the 1.6 TDI cam cover. Hand tools, a few pounds in parts, an hour.
Do it yourself if you have the kit: a vacuum actuator. That means a hand vacuum pump with a gauge, the adjustment kit for the rod nuts, and a tool that shows the position voltage. Without all three the rod gets set by eye and the code comes back.
An independent VAG specialist: a vacuum actuator without the kit, any electric actuator and the TSI wastegate actuator, because the basic setting needs VCDS, ODIS or OBDeleven PRO. On my Rapid, OBDeleven’s Free plan reads codes and live data, then opens the upgrade screen the moment I touch basic settings, so budget for one of the OBDeleven plans or the specialist’s hour.
The dealer: warranty claims. Wherever you go, ask for the numbers before you agree to a turbo: did the diaphragm hold vacuum, what did the sensor read with and without vacuum, did the lever move freely by hand. If they can’t say, they haven’t tested it.

Parts are retail listings checked in November 2026. Fitted figures come from owner quotes between 2014 and 2021 and VW’s own time of about 1.3 hours for the actuator; owners doing it themselves report three to four hours. US turbo figures are RepairPal estimates. In the US, check your emissions warranty before paying: one 2017 Golf in California had its turbo replaced under the 15-year, 150,000-mile PZEV warranty. In Canada, dealers charge about CAD 3,000 to 5,000 for a complete turbo over a seized wastegate shaft; a specialist’s stainless-shaft rebuild runs CAD 1,200 to 1,500 installed.
How to Stop P2563 Coming Back
Replace the vacuum hoses with the actuator. They’re the same age as the diaphragm and fail the same way, and a hose that goes six months later stores the same code and gets the new actuator blamed.
Put the heat shielding and loom clips back. A loom left beside the manifold chafes or melts, and the next code is P2564 or P2565.

FAQs
The turbo actuator’s position sensor reported a position the ECU did not command. On VAG diesels that’s usually a leaking actuator diaphragm or a vacuum leak; on the TSI petrols, the electric wastegate actuator. P256300 is the same code with sub-code 00.
Inside the turbo actuator on the turbo: behind the engine on the transverse diesels, in the electric unit on the vans, in the wastegate actuator on the TSI. Not the boost pressure sensor on the charge pipe.
Find the actuator type, hold vacuum on it while watching the sensor voltage, and check the lever moves by hand. Replace the hose or actuator that fails, set the new unit with a gauge, run the basic setting. A turbo only for a seized lever.
Nearly always it is. VW’s bulletin says replace the actuator diaphragm and sensor, not the turbo. The turbo is the answer only when the vane lever is seized or the housing has rotated.
For a few days. A diesel keeps its power at first but stops completing regenerations, so the DPF light follows; a TSI goes into limp mode. Stop if P0299, smoke or a loss of power join it.
