*HELP* engine fault code no garage has been able to help

[VW]

Hi guys I have a Volkswagen Golf mk5 gti. I recently got the timing belt, chain and water pump replaced. Ever since I have had the engine code camshaft positioned bank 1 intake slow response P000A not a plausible signal. My garage have stripped the engine and visually cant see any fault the car drives fine but feels a lot slower and requires a lot more acceleration than it did prior to this fault. The garage can’t figure out what is causing this and have consulted vag specialist but I’ve had no luck! They have potentially suggest replacing the cam shaft but there’s no guarantee the engine light won’t come back on. I was wondering if anyone has had a similar issue and have been able to resolve it.

A few of us have similar issues in the past, this thread might be helpful;

I did have a quick read through that but not sure if anyone was able to resolve it. My garage suggested that we could replace the camshaft but it physically doesn’t look worn and that the check engine light may come back on even after. Did anyone figure out what causes this fault code/ what resolved it?

If the fault occurred straight after the garage had done the timing belt etc. then I'd be looking at what they've done to cause it. I don't believe that this fault will just be a coincidence.

Sounds like the timing/belt is out to me........a sudden lack of power after the work was done, is setting my alarm bells off

As above, if it felt like that immediately after a belt change, it needs to go back to recheck the timing.  Nothing else would cause that fault code except a failed VVT adjuster or solenoid, which isn't common.

Just speculating, but maybe they ignored the timing marks and just paint dotted the old belt, cut it off and slipped a new one on.  The engine needs to rotated by hand 4 times and verify the timing marks still line up before buttoning it back up.

Hi all thanks for your replies. I thought the exact same thing and did take it back to the garage after which the stripped the engine and checked the tinting again which was coming up spot on. I then took it to a vag specialist for a second opinion and they suggested replacing the hub vvt and control valve but again weren’t sure if it would resolve the issue.

Just out of curiosity how much is a vvt solenoid replacement?

About £100 brand new.

I had the same problem after refitting a new timing chain. It turned out to be that when I set the timing I didn't place the chain in the correct place and count the 18 links back to the other sprocket.there is a vid on you tube of a guy doing the timing and explains about the links. Once I did this the code was gone and full power was restored hope this help
