Engine Warning Light on 2009 Vauxhall Corsa CDTi

I've had a CDTi Corsa from new in 2009, always been serviced, reasonably well looked after etc...

Around 2 months ago, the wife was using the car, and on her way to work, the engine management light came on on the dash, and the car went into 'safe mode'. She pulled over, switched the ignition off, restarted it, and no light.

We didn't think much of it, and it didn't happen again for around a month or so, when I was driving it, and the same thing happened (on the motorway), same again, switch ignition off, light doesn't come back on, car responds as normal. In the last month or so, this has happened several more times.

The 'fault' seems to occur when accelerating from 50mph to 70mph, but not when cruising at a steady speed.

When I took the car in for its MoT last week, I got the garage to plug it into the diagnostic machine, but there are no faults recorded.

Anyone got any idea what the problem could be?

Diesel particulate filter? My Daughter had one with problems with the DPF that then caused knock on trouble with the turbo, mucho cost later it got tossed in for a mini...with similar problems. Now drives a Polo with no problems (Touch Wood)

Curiously, I have a 03 petrol VW polo and since 2007, the engine management light has been illuminating and going out seemingly with a mind of its own all of that time.

I worried at first but now I just ignore it - it's a known fault with the sensing system it appears.

Engine management light illuminated is an MOT failure now so beware.

not fancy buying a blutooth OBD2 transmitter and fault code reader app for your phone (called torque) has many uses, includes live data so you can have auxilliary gauges displayed on your phones screen (boost,coolant temp,voltage and lots more) and it will work on all modern cars so it wont be money wasted

I can second the Torque app, it's quite good. Works on some cars better than others. As a corsa is basically a GM you might get quite a lot of data off it. I get more info off the wifes VAG diesel than I do my clio diesel. Plus it also does 0 - 60 times etc.

Craig/ Scoob,

I can see an app on App Store called 'Engine Link' but nothing called Torque... It's an OBD II monitoring app, and seems to do what's described...

Torque is Android only, things are a bit more expensive if you want ios compatibility. You can connect them to a laptop though

12 months is fairly hard on an egr especially if your doing city mileage, I just changed one on a mondeo tdci that had one already this time last year. He was a town taxi driver though doing no motorway miles/long runs what so ever.

Did you get an improvement from the cleaning for a few weeks?

I was doing 30ish miles a day, through town, then onto fairly fast flowing country lanes... When the bloke looked at it last week, there was a fair amount of oil (or similar gunk) in there, which he cleaned out, but 'the fault' happened again twice on my way home (approx 15 mile journey back home).

There was an improvement for a while, but tbh, I'm thinking it might be better to 'move the car along' before sinking too much more money into it...

On my ford a dirty egr valve caused rough idle and more smoke, no cut outs/limp home modes, got bored of cleaning it in the end so blanked it off, personally i doubt it'd cause your problem, although in fairness as its a newer car maybe the electronics are now connected to the egr??

The bluetooth readers and torque are good, but they wont get every fault, and nor will the 'snap on' type readers a lot of garages use, i had a fault that stopped the engine at a certain rpm, no limp home mode for me, but my reader didnt show anything, a mobile mechanics reader didnt show anything either but a specialist showed a faulty crank shaft position sensor (turned out to be sheared!!), within a couple of mins.

Is it always between 50-70 mph?, what gear?, uphill/flat/downhill?, throttle position? hot/cold engine?, any other symptoms, ie decreased efficiency/power, increased smoke, increased noise?

As there are lots of sensors etc on new cars it may be worth biting the bullet early and spending £70 or so on a specialist to check the code for you, rather than guessing and spending money on a guess/mates 'educated' guess.

It depends on what is happening with the egr valve. The op's sounds stuck open which floods the engine with exhaust gases and restricts the air intake creating a lean mixture. Once the ecu recognises this lack of air it go's in to limp mode. This is what happend on the mondeo, the egr was stuck open.

Yours may of been stuck shut which raises the temperature in the combustion chamber and leads to pre detonation, rough running and black smoke from unburnt fuel.

They can also get that choked up with carbon and crud it clogs the pipes up and wont start at all as it blocks the intake up. If you get a diesel non start that turns over but sounds as though its starved of air theres a good chane the egr is blocked or the cat.

Stuck open can cause poor idle too though. The egr should be closed on start up from cold. Id park it u over night then remove it the next morning and see what valve is doing. Could always blank it off, plenty of guides on line for you matey.

Same thing happened to me with my CDTI Zafira, after months of main dealer visits, changing bits various sensors, etc. it turned out to be failed rubber pipes on the vacuum pump. Under acceleration the pipes would suck themselves closed, this was sensed as a fault and get you home mode kicked in, as soon as you stop and restart the engine, pipes open up again and everthings fine. Spend a bit of time and check the pipe work, it could be an easy fix.

This could be it... I'll get my mechanic to take a look... Cheers!
