Diesel Particulate Filter Issues with the new Polo TDI
4 weeks ago a bought a brand new VW Polo 1.6 TDI Sel 90, the reason behind choosing the engine was simply down to practicality and running costs with its 78.5 mpg possibilities.
Only at the point of being handed the keys I was advised that these new diesel engines are all fitted with a Diesel Particulate Filter, they self clean so long as you give them a good run once in a while, which wouldn’t be a problem since it’s a 20mile carriageway commute to work and back each day.
Having had the car only 3 days and having already totted up 176 miles this filter light comes on, to be sure I understand the situation correctly I read the manual, which states this warning light appears when the filter is over 55% clogged up with diesel soot and that I should drive 45mph for 15 mins in 4th gear. I quickly realised the issues this causes:
1) 45mph for 15 mins is only possible on carriageways near me out of rush hour times.
2) 45mph in a 70mph zone is hazardous to other road users.
3) You are likely to be pulled over by the police for causing a hazard to other road users.
3) 15 mins at 45 mpg is neither economic nor practical, at best you can hope for is 40mpg
4) 15 mins wasted time is not easy for my schedule nor is it cost effective.
5) I am not normally available to waste time during offpeak hours.
This issue quickly grew as I neared 680 miles and had already repeated the above 4 times.
I never had VW Pegged as such impractical engineers? At this rate the 1.4 TSI engine would have made a more practical choice. Clearing the filter around every 1000 mile intervals would be fine but now at 1080 miles I have now done a filter cleaning run 7 times, much to my inconvenience.
Having reported this to VW, they were very vague and it took them 2 weeks to book me in for an inspection and courtesy car which, this happens to be today.
The vagueness of VW and the Nemours complaint I have since read up on across many forums leaves me a little unsettled with me issue and leave’s me wondering if this is an issues with “my car” or the entire “Polo TDI” range? I know nobody with a Polo TDI so therefore cannot share thoughts.
When I get my car back will this be ajn ongoing issue? Should I attempt to get my money back now while I still can and venture towards the petrol engine which by comparison seems like less hassle and the more economic option?
My cousin has the 2.0 TDI Scirocco which I know to have a DPF, he has exceeded 16,000 miles and not once has he had the light come on.
Reading into this issue I found that you do not really need to drop down to 4th at 45mph, the exhaust simply needs to reach 300 degrees, or, keep above 2000 rpm for more for 5-10mins to self clean, again this defeats the diesel engine, its purpose and can imply that driving heavy footed or speeding on carriageways seems to be the preferred driving style for the new unimproved Polo TDI?
I can find a lot of complains and misdirection but not a lot of advice on what to do or more information specifically on this model and this issue.
What can I do?
