Hi,
2007 Skoda Superb 1.9tdi Classic 115bhp. At say 40mph....coming to red light on level ground...footoff power but keeping in gear say third...chugging is evident, as if limited petrol is still being issued, revs seem to hold without dropping?. Just serviced, fuel filter ect... 73000 miles , taxi 1000 miles a week. First hiccup since Nov 2011 at 1K miles perweek with regular servicing each 10K and new timing belt at 60K miles?
What are the possibles on this one and how much to repair...list all variables please?
When time permits,
fonaspin

Are you saying this car is expecting 50,000 miles a year +/- of taxi service use? For this issue it is probably anything to do with air and fuel delivery - dirt or intake leaks. Code reading could help pin it down. You may even have a sludge problem and would check on that too,

You drive it as a taxi in town but only change the oil every 10,000 miles? Definately going to have issues. Right now I would change it and if you put on 1000 miles a week you should do it weekly for the next 4 or 5 weeks to help break loose all the crap that is forming up in there. Once you have gotten it good and cleaned out that way switch to a full synthetic oil and change every 4-5000. This definately qualities for severe service. In the US if you sell a former taxi they require the title be marked as such, just the same as former police cars, flood damaged or salvaged vehicle. Cuts its resale value in half and for good reason with the hard life it lives.

Hi,
Many thanks, yes in future I wil have oil changed every 6K miles. Im selling this car soon and will upgrade my servicing interval as advised for the new Greeline.
My maintenace guy says no error codes showing at all...he is to review tommorrow, but as I say new byer will solve and repair the issue ....I just wanted to know
what caused the issue...lack of oil change seems probable.
Thanks for the reply.

The 6k guideline only applies to full synthetic oil. If you are using conventional cut that number in half.

Thanks for climbing all over this Nick. fonespin - My own Bro pounded 1,000 miles a week and still does close to that in sales with more extended driving than stop and go taxi like but still the miles.
Always found used cars known to take a pounding and full synthetics any oil or grease in the things. Managed to get a good 250,000 out of them but were still suffering going close to 10K on oil changes as I couldn't talk him into dumping oil sooner. Slightly different as those were Detroit Iron cars and pigs on gas which wasn't so bad as low MPE = Miles Per Engine problems which so many cars were and more are now.
Best of best oils still get contaminated so even some liquid gold isn't going to stay the same over the tough miles.
Nick is right on as usual - change oil now frequently to clean it up is better than anything way too fast and cross fingers that it works out.
At some point every little thing that moves - locks, hinges, latches, windows seat adjustments, springing of seats, all suspension and steering parts just can't take it so if doing this work keep the next vehicle in mind as all that stuff will cost you down time even if you could keep up with all of it.
Gotta factor that in as a cost of doing business but can keep it to a dull roar,
