Car Advice re Engine Management Light

The Engine Management Light is showing on my 9 year old Nissan Almera.

There doesn't seem to be anything obviously wrong with it and my dad said to ignore it but surely it wouldn't come on for no reason?

It was last MOT'd at the beginning of June and prior to that I spent a small fortune on getting the chain and tensioner replaced, etc.

Would you advise taking it to the Nissan Garage to get it diagnosed again or is there somewhere cheaper?

Any advice gratefully received.

Somewhere cheaper - anybody with a generic code reader will be able to tell you the problem.

When I purchased my car (from new) the light came on within a couple of miles. Dealer said it was the battery terminal hadn't been connected properly.......so check all the electrical connections are sound

same thing happened with my skoka over the weekend. The previous time it happened, it was just a sensor that had gone which told the temperature. Theres probably nothing actually wrong though.

Where are you located? My other half could have a look at it for ya free. He has the engine diagnostics machine.

Try resetting ECU first, Just disconnect battery for a couple of hours, If it comes on again then have it checked.

I'm loathe to pay out £50 plus VAT for them to tell me it's nothing wrong!

Thanks Tara, I'm based in Gloucestershire, suspect you are nowhere close?

If the light is on, then there is probably something wrong (minor or major). The fault code causing the light will be read from the ECU and can be looked up in a book and then the problem part replaced. That's the theory of it, sometimes it doesn't work out quite like that. Is the car running rough at all?

No, not at all and my Dad said that it was running as smoothly as anything so seems odd.

Any smell of petrol to suggest it is running rich?

No, not that either and the oil level is still showing as well topped up, etc, etc.

As suggested above, I will suggest disconnecting the battery and leaving it disconnected for 10 minutes followed by reconnecting. This may clear the fault code which may be just an error of the system.

Otherwise I would recommend that you look at getting the fault code read to see what it is. On petrol cars, it is most usually a sensor or coil.

Okay, thanks for the advice, I will do as suggested.

On an astra I used to have the engine management light used to come on from time to time... got it checked out at 6 garages and they all told me I needed a new management system for approx £1500, didn't believe them as the car ran fine and the light only came on occassionally... anyway eventually I went to a different garage and they told me the same thing, but when i spoke to the mechanic he said he could take it to his friend (who works at a vauxhall dealership) and see if he knew what the problem was or for a second opinion. So he did that for me, came back 30 mins later with the problem fixed and didn't cost me anything... it was a sensor that was loose (lamda I think), so gave the guy £10 for his trouble so he could take his mate out for a drink :)

That makes me feel sick. My dad had a Vectra and was told same thing by them. Dad paid it too. :-(

My dad is pensioner.

That sucks... but in all fairness that could've been the problem with his.. I just knew that mine didn't have and would rather get more opinions about a problem than to just pay it... did the problem re-occur after your dad had the new engine management system installed? if not, then I'm guessing it really was the problem with his, OR, that they installed the new system and when the problem re-occured when testing they found the loose connection and made it right. There's just no way to tell which happened i'm afraid.

Right, took the car to a local garage who were going to charge £28 plus VAT for a diagnosis. However, I pointed out that I was going on holiday on Saturday so he told me to bring it in first thing this morning for them to do a quick check and it said that there was a problem with the Oxygen Sensor in the exhaust (no charge as it was a very brief diagnostic check) and he has reset the light and if it comes on again he will order me in the part at £70 plus labour. Relieved that it's not going to cost the earth like the last time!!!!
