Hi there,


I have a Fiat Bravo 1.9 150 Multijet, the warning light came on yesterday while I was driving on the motorway. I was doing 100mph and then decided to see how quick i could get to 120mph ( motorway was empty, night time).

Anyway, when i put my foot down, the warning light came on and the engine went into limp mode, lost power and wouldn't go above 70mph.

Stopped at the next petrol station and turned the engine off for five minutes. Warning light didn't switch off, but i could go above 70mph, however i had lost some power.
Then i noticed that the car makes a really low hissing/whistling noise.

Today i connected the fiat ecuscan and the following errors came up:

P0500 - Vehicle Speed Signal (CAN)
U0426 - Invalid Data From Vehicle Immo Ctrl Mod
P0094 - Fuel Pressure (high press, pump input regulat.)
P0237 - Turbo Pressure

The car was remmaped around two weeks ago, there was no problems with it, no smoke, the ride was smooth, everything was good. I have been on a journey to portugal and back, around 3000miles all together, and there was no problem. so im guessing that it has nothing to do with the remmapping?

also i only bought the car around 2 months ago from a dealer, it came with 6 moths gold insurance, which covers the engine and electrical faults.
if i need to replace/fix anything to do with these faults, would they come under the warranty?

I have cleared the codes, and they haven't come back on.

thank you

Good, serves you right your an idiot.

Empty motorway or not that's not only dangerous but illegal and you would be prosecuted and loose your licence being caught at that speed. You are a danger to other road users. There is no justifiable reason for you to be doing 120mph on UK roads. You think the law doesn't apply to you?

I don't think that at all. But I'm sure you haven't always stuck to 70mph in your life, even if it was by 5mph still makes it illegal. But anyway the point of this thread isn't about the speed I was doing. I know I was wrong but I don't need to be lectured by you.

Actually it doesn't. You get speed limit +10%, so 77mph is when it becomes illegal 100mph+ you are looking at a driving ban.

acpo guidelines only

i have known people get a NIP for 32mph in a 30 zone

have you tuned it?

turbo pressure + remap sounds a wee bit iffy there, if its pushing too much boost you may have popped a hose off or somthing

Thanks for the reply
Okay, what would be the best way to get that checked over?
Thank you

Thanks for the reply

I'm not sure what you mean about tuning it?

Actually over the limit is over the limit, and illegal.

However 2nd poster needs to take a chill pill! OP didn't even state the country he was driving in, could be away in Germany for all you know ATM.

If it hasn't happened again and it's driving normally I'd dismiss it as a fluke. I would however put the car through it's paces (where safe of course). And try and reproduce the error. If it happens again I'd be going back to the remap place as 99% sure it would be that causing it.

If you have FES i'd connect it up and monitor turbo boost pressure etc and see if it has any nasty spikes when on full throttle and full load.

There are a LOT of cowboys out there who haven't got a clue. Bought a £99 ECU mapper on eBay and think they're pros.

MPH and Motorway suggests its the UK. Chill pill? Not really, driving at 120 is idiotic and I am assuming you are not condoning this. Having been hit by an idiotic driver not paying attention and going too fast in the US earlier this year I now appreciate more how easy it is to cause accidents, and this wasn't in a car, I was on foot.

My dad and sister were nearly killed 3 years ago due to a stupid driver, and dads injuries are going to remain with him for life, so like you I know first hand what stupidity and recklessness can do.

It's not speeding that normally causes accidents, it's people not being able to maintain control of a vehicle, or not driving to conditions. So don't assume people are being reckless just for speeding. Although trained accordingly emergency drivers speed daily, doesn't automatically make them wreckless or dangerous drivers!

And for reference, when I and friends drive over seas, including Germany, speeds are still refered to as MPH, and motorways as that also. But perhaps that's just us??

Last Sunday I was driving up the M11 at 70MPH, I was passed by an Audi that passed me doing probably about 100, followed closely by a BMW. The Audi pulled over to the middle lane, and I could see something flapping underneath. Moments later the plastic undertray came out from under his car, flew up in the air with bits flying everywhere.

Fortunately nothing hit me.

Idiots who ignore the rules of the road KILL PEOPLE. Hopefully, when they do, its suicide, and you can do that on an empty motorway at 3 in the morning..

Yeah but you are dressing this up as something its not. Speeding causes accidents end of story. The distance you travel and reaction times all make it dangerous. You cannot predict catastrophic failure either which you are far and away more likely to survive at lower speeds. Do you think speed limits are just a number picked from the air?

People are killed by speeding drivers, there is no argument otherwise.

People are also killed by none speeding drivers, dangerous dogs, terrorists and cancer. Not everyone who speeds kills someone. As said its people who can't control it, or do it at inappropriate times.

Speed limits are indeed there for a reason, danger isn't the only reason though.

Other country's manage higher limits with less road deaths in some places - so go figure.

Sorry but there are so many logical fallacies in that statement I don't know where to begin.

Speeding does not cause accidents.....

inappropriate speed for the conditions/ road can Sometimes its not safe to do the posted limit... likewise people are killed or maimed by people driving under the speed limit who are not paying attention/ prating about with their phone/ Mis judging bends/ hitting spilt diesel/ Hitting un lit farm machinery/ Failing to stop at zebra crossings / jumping red lights/ driving defective vehicles


Speed can be a contributory factor however this Think road safety mob seems to brain wash people with pointless inane campaigns..



in that one

Hazard white lines..

Junction clearly visible

Car indicating

Cars position on the approach changing from left to centre line

So Why is it made out to be the car drivers fault
