Calling all diesel mechanics....HELP!!!

Have to agree with Quinny in his last post (10), go to a Diesel specialist you'll get exactly that, pot luck who gets to look at your car at the dealership.

The specialist will remove and clean the valve properly and surrounding pipework which will be well clagged too, on some cars cleaning will be enough for another hundred thou.

Interestingly it is reputed that long term regular use of Millers Diesel additive can help stop this sooting up, too late once it's established, though some call Millers snake oil, take your pick.

Rather than take it to the dealers, what about seeking out a local diesel specialist if you don't want to replace the egr valve yourself?

Get a costing from both of them, then decide.

thats one plan The longer we can put it off the more we can save first lol

The beauty of specialists is that they usually have a small compliment of staff, so care on the job is better. Dealers may, in certain cases, farm the job out to a specialist anyhow, and then charge you for the privilege.

Our local Chrysler dealers are not the best I have to say, we would usually go to an independent first.

Thanks for the link scotsman!

There is usually little tricks you can do to reset Engine Codes yourself. Sometimes you have to have the ignition in a certain position while pressing a pedal and operating the indicator or something stupid like that, have a hunt around Google to see if you can find anything It might well be a false positive, my Astra used to do it all the time, but has recently stopped doing it :rotfl:

Came across this on a Chrysler fault code website relating to the code 403:

"A problem was detected in the EGR solenoid control circuit"

It doesn't say what exactly it is, but I reckon my earlier diagnosis could be not far wide of the mark, but I also found that to clear the code, disconnect the - terminal on the battery for a minute or two and the code should clear. You will also have to reset your time clock and any other things that rely on the battery.

Obviously the code will re-appear if the offending part is not replaced, so that needs doing first.

If you are finding that the fault comes and goes at random I would look at the wiring. The comment about the EGR solenoid control circuit should help. Find the wires for this circuit and give them a good tug. You may find that the core of the cable is broken but the pvc insulation is not. You will know when you have the broken one.

For reading and reseting the fault code you can buy an interface from your car to your computer. I have the ELM327 which cost about £30 or look for OBD reader.

Thats interesting, and more detailed than we have found for that code. OH sprayed the control circuit with WD40 last night shortly before the light went off so I wonder if the problem is there rather than the unit itself? hmmmm

Incidentally, we disconnected the battery and have left it off all night in an attempt to sort the central locking issues, so hopefully the code has cleared now

What are the issues with the central locking? There have been issues with poor earthing which can lead to multiple problems.
