Hello guys .

I sure this has been spoken about but I cannot see an exact match , so here goes .

I have a 1.6tdi 105bhp ( remapped but issues where there before the remap ) .

I do 18 miles to and from work a day and it is motorway and dual carriageway roads so a contant speed is keep .

There are no logged faults in the cars system .

I tend to keep the revs higher after reading some other posts on here .

But the car Is regenerating on average twice a month and when it does,  it drives like its powered by kangaroo juice .

And now I haven't used the car for 4 days and it is now doing it again ( was fine when I stopped using it ) .

I am after any advice on what I can check or what the issue may be ( I have access to odis to check faults etc ) .

I love the car , but this is really getting on my nerves now .

 

Any help would be greatly received .

 

Thanks 

I would start by cleaning out the EGR valve and pipework since the problems you describe are generic and common to most modern diesels with DPF.

Thanks , thats a good start . I'll get that done .👍

Depending on actual engine code, VAG DPF free for Android may give you basic info on your dpf and regen status via a bluetooth OBD2. There is a paid version but the developer suggests using the free version 1st to check compatability.

Thanks Keith,  I'll have a look at that now 👍

So this is the read out I have had , please excuse my ignorance , but is this OK or is there an issue .

Thanks 

It's almost entirely meaningless I'm afraid.

 

There's no substitute for getting your hands dirty.

it's not what you think it is. EGR is not accessible without dropping the subframe. Worth replacing instead. But then you need to do an EGR adaptation.

Just because it's difficult to do doesn't mean it's not worth doing, I don't consider the cost or practicality of the advice is relevant to the problem itself, most people start by doing the easiest or cheapest jobs before eventually finding the correct solution to the problem.

wasn't that EGR a poor design anyway with it's issues? Removing something that is hard to access to then break again, surely you wouldconsider just replacing it?

What is the engine code ?

 

You may be able to fit an EGR emulator which would be a lot easier & cheaper.

Or go back and get it mapped out.

 

I should have gotten mine mapped off with everything else. Ended up putting a restrictor on the egr pipe instead.

+ 1 for an emulator assuming there is one for that engine.

 

Plug n play and no issues to date, if ever I do have problems and suspect it then its easy to remove it from the circuit by removing and repositioning 2 connectors, albeit one in a difficult position.

The engine code is CAYC .

 

thanks
