The "check engine" light has come on on my 1.4 TSI. It drives fine, and I accot hear any odd noises, but VCDS gives code P0016. If I clear the code it comes back on after a few miles.

Measuring block 091 (camshaft adjustment bank 1 intake) reports 19.5 degrees KW B1.

Not long ago the car had occasionally been difficult to start and gave a camshaft/crankshaft "improbable signal" error, but that doesn't happen anymore.

It has done 95,000 miles, and it had the timing chain and water pump replaced at about 45,000 miles.

Please can someone tell me whether the codes suggest that it's time for a new timing chain, or might it be a problem with the sensors?

You are on the right track

Thank you. Does the fact that I'm getting a camshaft reading (19.5 degrees out) suggest that the sensor is okay, and the chain is the problem? Or impossible to predict?

When was the oil changed last and is it at the correct level. Think that engine has variable valve timing and I read that low/poor engine oil can cause oil control solanoid not to work properly.

The oil was changed two months ago when it went for its MoT. The level is correct unfortunately.

Might be worth changing cam sensor first but it does look like a timing issue. I wouldnt be driving too much if at all until its checked. Last thing you want is for it to jump a few teeth. I assume they used the correct oil last service.

Thank you Alasdair. I'll get it checked.
