Hello

I am relatively new here, I am not sure where to post questions like this one, if the bar isnt the right place, apologies.

In carefully reading the VCDS documentation I see it mentions that controllers have workshop codes.

"identifies the WorkShopCode ( WSC) stored in the scan-tool that performed the last Coding or Adaptation procedure in this Control Module."

Two quick q:
What is the reason that this is stored (for example is it just for an audit or does it have a functional purpose beyond a record) ?
What would the advice be to set this to if a "home" user makes a modification please ?

Thank you for an awesome product

The first step is to do a full code read of the car and save the file somewhere safe so if you make a coding error, it SHOULD be a matter of copying and pasting the original coding.

Thank you and I agree, however I guess I could have made another thread which read "how to do a full code read of the car"; but having done that the questions in this thread would still be valid. If you happen to know the answer to the questions in this thread that would be gratefully appreciated.

The intent of workshop codes was for the car to have a record of what workshop last made changes in a particular control module. However, they have no functional effect.

Leave it in "stealth" mode unless you encounter something that won't accept it.

awesome. thank you Uwe I have now read the FAQ.

(offtopic)
While reading that I am reminded about label files. the autoscan of my B5 Passat 1.8T 20V saloon year 2000 3B chassis ross-tech appears to be saying it doesnt have a label file for the engine so I will try to help Ross-Tech create one for that engine in due course.

APU is your engine code? ("Auxiliary Power Unit" -- LOL)

The 4B-01 re-direct file implies we should have one, but I'm not finding it it English or in German. :confused:

APU 034974 it is..

UK right hand drive

(The main engine is a Star Drive Warp Capable powered by the aux power unit)

I just uploaded a full autoscan diag level 2 to support@ross-tech.com as per the wiki for Redir Fail label issue.

If it helps the page from the service book is in the attached photo.

The biggest killer of these cars was sump sludge, that is why so few 1.8T 3B Passat’s and 8D A4/4B A6 remain; the numbers we saw fail were unreal.

Yep, the factory's oil change intervals on them was simply too long, especially in Europe, where they used "flexible" intervals, but even here in the US where they were on fixed (10,000 miles?) intervals, we had some problems with that.

Thank you for pointing this out. I have just paid an excellent shop for the full service inc oil and filter. I am happy to spend money on this new acquisition within reason esp as you say they are rarer. It seems it needs care with its age. Spend money on items that preserve it or derisk onward mechanical issues primarily. I was reading that changing the oil pump for new may be a good a good idea.
The central locking isnt a preservation item, just annoying.

The pain with the longitudinal 1.8T is the subframe has to come down to drop the sump but I saw some real horror stories in the noughties. I had an automatic 3B in where the turbo had failed twice and the turbo rebuilding company asked us to take a look why as the fitting garage insisted they had removed and cleaned the sump. When I took it apart I found they had used A LOT of what smelt like windscreen sealant. Thankfully the engine survived.

Btw the question perhaps I should have asked is how would you know your car had a problem building up in this area

Thank you. That is a tough call for a car that has no symptoms as a preventative measure and not std recommended service item to cost justify then.

When I rebuild them I go 2 litre but for the last 17 years the 1.8T I put in my Octavia when I bought it at 3 years old seized, it has refused to fail. The reason it was seized and the turbo FUBAR was the sump being full of sludge.

Where does the sludge come from in the 1.8T ?

If you service the car every 10,000 miles at a good garage including changing the filter will it still build up ? What makes up the sludge constituents ?

Passat engines (never had a 1.8T before) can go for 500,000 miles (the rest of the car falls to bits first). I had another B5 petrol saloon in the past some time back; I got over 250,000 until I crashed it (my bad). I had it serviced every 10k in line with VW recs
