Engine: TDI: P001D and P001E codes

[Mick9264]

Hi all, I own a V70 2.5 TDI from 1999 with 204k on it, the car was bought as a spare knockabout here in Spain where I live but I seem to have become attached to the old girl. I managed to get a scanner to read the codes as the EML was on and came up with p001d and p001e which is the camshaft profile control circuit low. I'm just going to check the cam sensor wire and the timing belt tension as it's not due a new one yet but worth a look, is there a common cure for this or am I just going through the process of elimination? I plan to get the belts sorted in the next month or so for peace of mind but that's about it as the previous owner had the old girl serviced regularly and was the only owner. Thanks in advance. Mick.

It would be worth concentrating on the belt tension and the timing of the valvetrain, before delving too deep on this.

I believe that these codes will flag if the cam timing is slipping relative to the crankshaft, so you need to be sure that the belt is tensioned correctly.

One thing worth checking, albeit that it is not easy to do with the vehicle on the floor, is to ensure that your crankshaft damper assembly is properly bolted to the end of the crankshaft, with the correct bolt pre-load and special friction (diamond encrusted) washer. If the TV damper is slopping back and forth as the engine runs, it will give the impression that the cam timing is incorrect.

Also check your dynamic pump timing.

If you even have a flat wheel on a P1 TDI, then the first thing that you need to check is that the pump timing is set right lol.
