Vauxhall 1.3cdti diesel-new EGR valve-spanner warning STILL on???!

DEBTMONKEY1A

Hi all,
Due to work issues not been able to take car to garage that originally replaced EGR valve. Just a bit more info, done 2 trips (45 miles each way) to Manchester Airport-all motorway driving bar 2 miles-speed 50-65 mph-primarily fith gear-NO warning light came on at all-so thats FOUR journeys at 45 miles each trip-no warning light at all???! However, on ALL my shortish trips to town, etc...as soon as engine is up to 80 degrees (warm)-bang-on it comes???! My style of driving is more aggressive (overtaking etc)...does this give ANY clues???? No 'limp' mode-driving feel & sound the same??
Hope to have it in next week to get it fixed.

Did they have DPF's at that age? Can't remember.

Just wondering if it could be the leak off pipes?

Hi-no DPF fitted on this. Sorry to be thick but what are 'leak-off pipes'??

You need to get it on to a Tech 2 (Vauxhall computer).

Of interest the CDTi Meriva i spoke of previously came back with that spanner light on and it turned out to be a temperature sensor on the exhaust faulty.

If you're not using Tech 2 to read the codes, you're basically guessing.

Paul-thanks for that! Soz to be thick (!) but is a 'tech 2' ONLY available from a vauxhall garage?

harveybobbles

No.

Tech2 is used by lots of auto electricians. Just phone a few up and ask.

Maybe contact a diesel specialist - they will be best.

Not that it'll make much difference but they only introduced the 1300 CDTI into the Corsa in 2003, before that they were 1700 DTIs and DIs.

A Y plate wouldn't have the 1300 CDTI.

Hi,

Was wondering if any knowledgable people could advise? I have a y reg 1.3cdti 4 door car-970000 miles-fully serviced. Also it has had a re-map for economy-which by the way makes it a fab car to drive-loads more torque (!).

I've had intermittent starting issues with it since I bought it-obviously more so when cold. It would always start after 7/8 tries (black smoke when fired up!). Occaisionally the engine seemed to 'stick' (ie put foot down-no increase in revs)-this usually freed itself up in a minute or so & was very occaisional. However-last week on a short run it was VERY 'chuggy', lumpy-barely managed to get it home & also would not go fast at all. Next am.-would not start at all. AA guy came out & diagnosed a faulty/sticky EGR valve-which he disconnected to allow me to get it to the garage.

New EGR valve fitted (was apparently really clogged up!)-luckliy have AA parts/labour insurance & they coughed up-so I only pay £35 (result!).

Car now starts miles better but still never on 1st attempt-usually 2nd/third & drives MUCH better. However...the 'spanner' light comes on -but ONLY when its fully warmed up. Trying to reset the ECU by turning engine off for 2 minutes doesn't make any difference-still comes on. Took it to a diagnostics splace-with spanner lit-NOTHING-no codes at all???! Guy at the garage thinks it might be a faulty fuel filter casing-allowing a bit of air in-he said there was evidence of a very small leak from under the fuel filter housing?

A bit more info-4 new glo-plugs put in this March-full service (the vauxhall big one) in February (all filters changed etc etc), battery fine-alternator fine. I do however do short journeys which I know is bad for a diesel. Also when spanner on car is not put to 'slow' mode-its just as quick.

Tried doing the 'pedal' trick-but did not seem to cause flashing of spanner light ??! (& anyway-no codes stored!).

Anyone got any ideas? Also considering buying some wynns EGR cleaner-as I always seem to do short runs-worth getting garage to spray it through (as its for trade use only I think) at service times?

P.S. The spanner light would come on intermittently when EGR valve was faulty-almost always went out if turned engine off for 2 mins-now on all the time-but only when fully warmed up.

PPS-As only do shortish runs-water in the fuel filter?:beer:

take it out for a blast on the duel carrageway once every 2 weeks at least

I'm guessing the computer reader WAS tech 2 as it identified the 2 faults?? The problem is-WHAT is causing the faults? Yes red eye-I've started doing that already-good blast on the m62! I get the oil/filter changed every 6 months & have seen that you can buy an EGR cleaner (for trade only use)-so will ask the mechanic to use this every time oil/filter/service is done.

Will keep you updated-again thanks for all your help!
