I've been following with interest the forum thread about VW's emissions issues and the quandaries it creates. I, and a lot of other people, are experiencing a different problem with the company. This involves the biturbo diesel engine installed in the T5/6 Transporter (in my case a California camper). I thought it worthwhile posting this firstly, to alert people of the problem and, secondly, to see if others on the forum are experiencing similar problems.
Age and milage of effected vehicles varies, but in my case my van started to use excessive amounts of engine oil into the 4th year of ownership (end of warranty) at about 40,000 miles. Now, at over 5 years old and 60,000 miles it consumes 1 litre of oil every 400 miles. This is apparently due to the exhaust gases passing through and corroding the EGR, carrying harmful Al, Fe and Si particles back into the induction side of the engine and scoring the bores. Extended oil change intervals have exacerbated the issue.
Resolution of this issue involves a new engine, EGR, DPF and catalyst amounting to circa £10,000 expense. VW's contribution to this is "Tough!" Suffers of this issue include 850 owners on a specific Facebook site about the issue, new engines for the Norwegian ambulance (160) fleet and many reports from other Europian countries. Most tackle the issue with their dealer who offer varying "goodwill" gestures matched by VW Customer Services. Apart from the circulated official "fix"for the issue, there is no official recognition by VW that there is a problem. Late vehicles with the latest EGR are suppost to have resolved the issue, but time will tell.
Legal enquiries confirm that the contract is with the dealer, not the manufacturer, so it appears that we are, for the greater part, on our own with our own individual battles.
