vtr in limp mode

21st February 2013, 18:59

hi everyone im buying a vtr in a couple of days only paying £200 but has some tasty parts on it but the body kit is terrible main problem it that the car will not go past 3k just hits the limiter i have checked the coil pack and it has made no difference. i wasnt aware that the saxo's went into limp mode. the eml light is on if thats any use and its a single plug vtr

Without diagnostics anything we can say would be a guess.

But may also not be limp mode could be the knock sensor detecting a knock in the engine and limiting revs to stop a big internal failure.

okay cheers what are the commen issues the car was running ok until a test drive drove fine went to park up then it happend

There are no "common" issues every car is different. You need to get diagnostics done on it.

Reset the ecu, and see if it still does it.

Try unplugging lambda's.. if that solves it, it's a dodgy sensor.

21st February 2013, 19:16

Plugging a code reader will probs be the best bet tbh

Off the top of my head my guess would be the map sensor though

FFS, Plug it into diagnostics, why even bother doing anything else its just guess work . The eml is on so there is a fault logged, plug it in find the fault.

But if we are guessing I would say crank sensor, Map sensor, lambda.

yer so why not go through the basics before paying some mug in the garage! the options i offered are free and simple

also if you use android you can get a bluetooth dongle that plugs into the diagnostics port and then a app called torque will give you all info you need forever for 10 quid!

BETTER?

No not free and simple, Say you unplug the lambda and the car runs fine so you replace it and the car still does the same. It could be the map sensor is fucked so over fuelling and coking the lambda up giving a false reading. Nothing is simple when it comes to the eml, Cheapest option is to get it plugged in.

21st February 2013, 19:36

Right I don't wana pay for it unless I have to. I have unplugged batt for 1hr with the same result I will try unplugging the lambda see what happens if all else fails il get it plugged In

21st February 2013, 19:40

unplug the battery (both leads) and lambda's (will clear ecu) then go for a drive if its ok then its that if not then you might have to pay (even though i wouldnt i only pay for mot and tracking EVER)

21st February 2013, 19:48

Yha il give it a go, I do have a code reader but I trapped it in my door and the plug is like mash up

21st February 2013, 19:53

cant you like un mash up the plug? then wont need to do anything else but use that

21st February 2013, 20:09

It's bad lol it's the USB side like bent in half just thort I ask on hear il give all the checks if no go will get it plugged into the computer

23rd February 2013, 15:16

right i have brought the car today tha has left me a bit skint i have unpluged lambda sensor and battery still no joy have clleaned all the sensors up and nothing seems to sort it not even for a slight min it just stays in limp mode any ideas i can not afford to get some one to read it yet for me

Why did you buy a car with a problem when you didn't know what's causing it.

As I told you the other day unless you plug it in it will cost you more swapping sensors than it will to just plug it in

23rd February 2013, 16:22

Have Plugged it in to the latest snap on mechane all that comes up is p1000 any ideas

That's not correct unless you have just bought a ford?

23rd February 2013, 18:10

nope its defo a saxo and that was the code, there was 2 things we had to do the 1st thing was we connected it and it said cannot connect to ecu, the secound thing is where we got the code i take it the 1st option was more advanced

23rd February 2013, 22:46

check fuses for diagnostic socket mate inside car passenger side check your user manual it will tell ya

Are you having a mate scan it?

Single plug ECU's do not have OBDII software... it's older than that.

You need a Peugeot/Citroen capable Scanner. I think it's OBDI

It could be your ECU is buggered.

24th February 2013, 07:43

Right I will check fuses, it was a garige that scanned it. He said it was possible the ecu, I will try and grab one but what will fit because its single plug with nO immobiliser

If it's the same saxo as in your display picture there, it does have an immobiliser. ALL 106/saxo's have immobilisers except from very very early 106's.

You'll need an unlocked single plug ECU if you want to try that.

Not convinced it's the problem, but it's one of these "possibilities" :/

trial and error can be expensive.

24th February 2013, 18:02

picture is on page 1, i dont think it has an immobilser, its on a y reg.. as a plan im thinking of swapping it from a single plug to a 3 plug is it possible to remove the engine loom without removing engine and will a 3 plug loom work on a single plug engine

24th February 2013, 19:23

Y reg definitely has an immobiliser, that's why you need programmed keys!

Yes physically the engines are the same, so you can fit a 3 plug engine loom and ECU to your engine.

Yes you can remove the loom without removing the engine.

25th February 2013, 03:42

ive got an unlocked 3 plug ecu if your interested and loom if interested?

25th February 2013, 07:25

Price mate? Il take a picture of the key but it don't look like it has a transponder even tho the car is fitted with a clifford

I'm telling you it has a transponder. ALL 106's have them from 1996 onward have an immobiliser and so do Saxos as they're the same car!

It's inside the case of the key, about 5x3x2mm.

25th February 2013, 18:12

yes mate it does sorry but back to the issue tryed getting it scanned by 2 places both can not connect to ecu any ideas

25th February 2013, 20:24

Yes you have bought a nail.

Most places cant connect to the early single plug saxo's. Citroen dealerships can because they have the correct software.

25th February 2013, 20:54

It might be a nail but the brakes alone are more than what I payed. But that my choice if I want to waste my money on French tin I can. But I am here for advice or to give advice. So what are my option's from here. I will utter refuse to pay dealership prices when it's going to be Somthing silly. Back in the day there was no computer diognostics they used good old skill soo any ideas people

25th February 2013, 22:37

Jay I've just read the rest of the thread properly lol, and the p1000 code is basically an unknown fault, but nearly always ends up being an ecu problem. Try resetting the ecu by unplugging the battery for an hour or so, if that don't work then check for breaks or loose connections in the wiring loom, If there's none then it's probably new ecu time tbh

26th February 2013, 07:03

Ok cheers pal, I'm off up scrappy today to get new loom and ecu I will be undefeated lol if that fail's I'm just going to 16v it

26th February 2013, 07:20

If you can then start the car up in the scrappy and take the immobiliser box out whilst it's running so you unlock it, otherwise if it's not unlocked beforehand you'll just be forking out more money to have it unlocked afterwards

26th February 2013, 07:56

Yes I know. Start car. Remove black box from dash, turn car off. Il go and see what I can get today I'm hopping to get the transponder with the ecu saves having issues at a latter date

26th February 2013, 08:03

If your taking the immobiliser with it then you'll need the ignition barrel too, there's some sort of chip inside it which is linked to the immobiliser, so you'll need the ecu, immobiliser and the ignition barrel too

I have exactly the same problem on my saxo vtr got the code p1000 still not managed to sort mine out

3rd May 2013, 09:25

I had my single plug gti scanned last week brought all codes up no problem although I had a autoelectrian not just some garage with a fault code reader

Did you manage to find out what the problem was
