Hey,
I'm having a bit of trouble with the car. This has been an ongoing issue for the last year or so. The car is fully driveable and such, but now that it has been colder, the issue starts to appear much more noticeable.
Model: 406 2.0HDI 110
Year: 2001
Motorcode: RHZ
Note: Fitted with a 1999 BSI and ECU
When driving the revs would randomly "spike" revving up and staying for 1-2 seconds before going low again. This could also be, that I removed my foot from the speeder, and the car would hold the revs without going back to normal before I slow down.
Now that it is cold it runs high idle around 1200-1300rpm going up and down a bit. When I do a cold start, it's also very easy to stall. This means I can't get the car moving without giving it some gas.
After reading the faults, the following keeps coming back:
- P0402 EGR-valve, positive deviation
- P0221 Throttle/position sensor; compliance between wire 1 and 2
(Those are translated to my best)
I have a spare Throttlebody which I've swapped with no effect. When opened I can't see anything wrong, but might not know what to look for.
The EGR valve "should" be clean, after haven got a "HyDrive" last year, which is cleaning out the exhaust system with hydrogen.
But to be sure I'm planning to remove it, and cleaning it with some EGR Cleaner. Is there a way to test it, to make sure it's opening and closing alright?

Just a thought but you haven't got air in your fuel line have you, that can do things similar to that. Fit a clear section of plastic pipe in the input line to the filter and check for bubbles.

Re: 2.0HDI Revs out of control and high idle
Sorry for the late response. Can air in the fuel line provoke the same behavior?
Example on my issue:
Going around 60km/h in 4th gear.
RPM is around 1600
Press the clutch
RPM goes up to 2100
after about 5 seconds, it will drop to around 1k.
I Will try to get a reading out with the tester, so it's easier to understand.

Might be the clutch switch borked? Hmm, that'll give a high idle at rest but not sure about at speed.

My car is having exact same issue, did you end up managing to fix this?
Re: 2.0HDI Revs out of control and high idle
I'm having exactly the same issue too - did anyone find a solution?
