2000 V70 Starting Problem

[GrahamB]

2000 V70 Classic 2.4 170bhp 108000miles
1. Have got it booked into a main agent next week to investigate an intermittent starting problem. (££££££££!)
It is normally a first time starter, but occasionally fails to start. On many subsequent crankings it fires for half a second and then dies. This can occur when the engine is hot or cold. So far I have always got it to start eventually, sometimes by leaving it for a while or by flooring the accelerator. Once running, it has not failed - yet. The agent’s receptionist mentioned the possibility of a dirty throttle module. Someone else suggested that the immobiliser gets its knickers in a twist and I was advised to try turning off the ignition, locking and unlocking the doors and trying again. This actually worked when it happened this morning, perhaps coincidentally?
I would appreciate any thoughts or advice before entrusting it to the tender mercies of the agent?
2. Incidentally, I have had the car for nearly two years and have asked them to run it through VADIS and report. They will do this and give me their own report on the findings, but refuse to give me a copy of the VADIS printout. Is this normal?
3. Another issue – the car falls into the years for the fan problem recall, but the agent advises that it is not necessary on this one. Is there a list of these chassis numbers available?

I've been through this with my '99 2.4T

The problem was a poor connection on the immobilizer anntena ring, this is round the ignition lock barrel.

You can gain access to it by removing the lower cover from the steering column.

The resistance of the coil should be 5 ohms +/- 10%

Check the coil resistance and the illimination lamp for poor contact.

Just removing the conection cleaning it and replacing it should do it.

Be careful not to damage the orange wiring to the air bag.

Hi Chris, This info has helped get my 1996 945 LPT going. Thanks.

Chris,

I have a v70 with a similiar problem but the car will start and then die. RPM to 1200 and then directly down to 400 then quit. Will not start again unless I turn off the key and turn it back on. Keep trying and finally it will idle and runs fine. I sometimes cannot get the key out. I will clean the connections and then clean the shifter end to free up the unlock cable. Do you think this is the problem, bad connections in the immobilizer ring??

Your problem sounds more like a dirty throttle body.

The immobilizer problem is either no start or runs for 2 seconds then stops.

Morning all, I am having this problem, I started the car this morning, Started fine and ran for 30 seconde then cut out, Message displayed was "service alarm system" & "Immobiliser fault" Then it wouldnt start, Starting for approx 0.5 seconds then cutting out and immobiliser fault consult manual displaying I have took the antenna ring from around the barrell and the little blue bulb has blown, Im assuming this is for when its dark so nothing to do with my problem, Then i got my multimeter on the pins of the antenna ring when connected, Getting some readings on all of them, Then wiggled the connector and got no readings, Can anybody shed some more light on this from past experience, I think my antenna ring is ok, Its the block connector at fault, Im going to try and stiffen the connections up somehow but any more advice would be greatly appreciated, Thanks alot. Nick.

Have left the battery off for a few hours and have just tried again to start the car, It is doing nothing now, It turns over but nothing, not even the half a second running then cutting out, Its just turning over, Anybody? Help!

[pillapow]

Turns out there was no petrol in the tank and my fuel gauge was giving a faulty reading. What a no-brainer. !!! But why would it throw up immobiliser and alarm system messages??
All running now, Nearly bought a new antenna ring for £30, Before i did i removed the pipes from the filter underneath the car and primed the system, few little drops came out, Cannister of juice later and happy days.

Having similar problems however since the last week it has become rather constant in the sense that in the morning at 6 AM the car does not start 9does crank) and in the afternoon when i return from work with enough daylight and time the car starts perfectly.

We are having quite some fogg here in the morning at the moment so i suspect humidity has to do with the problems.

After a fail to start (in the morning) a parasitic draw empties the battery.
Battery condition is fine (can do several start attempts and also had it tested)
Car cranks and gives the suggestion of a normal start (for a split second)
Continuing starting does not give this suggestion again
Remove key and put it back in again gives the suggestion of a normal start (split second)

Spraying start help in the air intake does not give a reponse.

Will measure the antenna ring tonight howerver suspect it will not give a result.

Previous owner had the antenna ring replaced (equal problems) and even had the connector to the immobiliser replaced in an attempt to solve this problem. Am having teh car now for two years and drives fantastic in summer and has this starting problem in autumn/winter.

Any tips where to search?

Problem is in the afternoons when i have time and light there is no problem so very difficult to find. ODB reader does not show any fault codes.

I had this when i first got my v70 and it drove me mad, i was worried about driving anywhere and not getting the key out and then having to leave teh car free for the taking.

With mine it was nothing to do with the key or the ignitition barrel it was the auto gear stick button. I noticed it was stuck in, so i teased it out and the key came out. I am now careful with the button on the gearstick to ensure it pops out again when i park and the key comes out evreytime now.
