Re: car security faiure warning light

How are you managing 80/90mph without the turbo?

My old 115 JTD lost all boost and it would not do 50mph.

Sounds like you have water in the fuse board under the bonnet. Try removing it and drying it out over night on a hot radiator.

Re: car security faiure warning light

First if your battery is new , check the alternator (charging)
ABS/ASR errors are caused by flat battery.
Car security i saw once, after forgetting to connect D4, so you can check it.

For the limp mode - unplug your maf and drive, if no difference - unplug your MAP and do a short test drive.

Off course a DTC scan with FES would be the preferred method

Re: car security faiure warning light

Water in the engine fuse box behind the battery or in the D4 connector under the fuse box could cause all these problems.

Re: car security faiure warning light

Took fuse box behind battery off & apart & cleaned & dry'ed it.Part of the circuit was corroded & looked wet.Obviously water got in from the puddles which gave me the immediate problem of car security failure,which is now sorted.Thanks guys.

Re: car security faiure warning light

If the large black plastic cover over the battery and fuse box is missing from your car, this could make it more susceptible to water ingress.

Re: car security faiure warning light

Its quite difficult to slpash water from the wheels into the engine bay fuse box if all the covers are in place, are you sure it was a puddle? The most common reason for water to get into the engine bay fuse box is using a pressure washer to clean the engine bay. Have you or anyone else used a pressure washer in the engine bay recently?

If so its probabely the cause of you problems.

Re: car security faiure warning light

Left my battery cover off once while doing something under the bonnet. On the way back from a test drive I went through the car wash. Got about 200 yards then Christmas tree and kangraroo.

It's not only a pressure washer that can force water in.

Re: car security faiure warning light

I've never used a pressure washer on my car.I haven't got a battery cover it got broken by a clumsy mate of mine who stood on it!Going to sort that out but my main problem is engine check light stays on & have no power,seems like turbo's not working as i cant hear it! Revs stick in all gears but 5th. Done the maf & blanked egr.
