Would have been interesting to hear how they came to conclusion that there iare two failed components.they are now saying it need a new adblue pump and injector
Whats your thoughts on replacing them ?
The workshop states onlyif i would have to bleed the adblue through with VCDS ? on test

Hi Drew. Sorry for not replying….just getting some weeks of driving to check the MPG. Having given it 3 weeks with 2 fill ups I can say that the mpg is same as before. I’m not the most ‘economic’ of drivers with 20’s and 275/40 tyres so I’m sure it would be slightly more.Have you found the mpg the same with it mapped out
Cos when the 650 warning light on it drinks diesel like I drink beer on a weekend by the barrel
ThanksStumbled across...

Leakage in the SCR system and AdBlue escaping? First check the AdBlue supply line. Find out more on course of action here.www.hella.com
Thanks for your reply and advice I’m going to do a few checks but I’m not going to throw a load of money at the adblue so looks like it might get deleted but at the moment the light is not on I’m holding off just in case Vw have fixed it by doing tests on it it’s a long shot but you never knowHi Drew.

the main thing is NO MORE ADBLUE!!!!!!
good luck everyone with any issues but if you start to get issues, the chances are they will return and be expensive

See my recent post about Dave Tec in the Trade / Forum Supporters section. Had my 2018 van from new and 5 years on and off of Adblue and EML issues relating to EGR valve (cleaned twice and eventually replaced by VW under warranty) and Adblue level sensor. The problems continued, and Chris has sorted it finally.Have you found the mpg the same with it mapped out

Yep, that’s the oneHi do you mean this post ?
Just a short post to pass on my thanks to Chris for his EGR and Adblue solution which he applied to my 2018 van last week. I’ve had trouble with both since new and VW never quite got it sorted. I’ve kept an eye on the forum for 5 years of problems folk were having and then my turn came for the ‘600 miles to no engine start’ message to display. The remap has transformed my 102 van. I live in Cumbria and the constant up and down gear changing between the gears has been reduced dramatically around the lanes. A 300 mile motorway trip has seen mpg increase by about 2mpg as well. Good crack as well with Chris, thanks for the cake! Recommended.
Correct. Be worth getting in touch with Chris at Dav Tec and he’ll talk through your options specific to your van and issuesMattn
Not engine BHP remap
Document - VW Service Training, Self-study Programme 424: Exhaust Gas Aftertreatment System, Selective Catalytic Reduction, Design and Function - states the following:there was NO Adblue at the injector when I removed the dosing pipe it was dry and no crystallising there at all
What does VCDS report for measurement valuemaybe it could be the pump ?
