rover 75 diagnostic

corner back 2

I have a 2004 Rover 75 2.0CDTi. My only problem is that the airbag warning light is on. Apparently some modern diagnositic tools dont work on Rovers. Anyone know of somwhere in Dublin or Carlow/Kilkenny that could fix this for me?
Thanks in advance.

I would bet that it is simply a bad connection under one of the front seats. You can have a look at this yourself. If that is the problem, the light will go off itself when problem is cured, no need for a reset.

Care must be taken when working on airbag system

I've got a 2002 CDT Tourer, and you're right, a lot of information can only be read out by a T4 Rover Testbook. However, I know a garage in Cork who has Rover Diagnostics which work fine, and even though they can get their hands on a T4 when they need it, they never need to because their own rig is so good.

Thanks for help guys. Will check out connections under seat craefully! Unfortunately Cork is too far for me, so I am wondering if anyone knows of good mechnaic in Carlow/Kilkenny area or Dublin 7 area who specialises in rovers?

Ger murphy Herbron ind est kilkenny is very good. he auto elec:D

Doesn't matter if an Autoelectrician is good if he doesn't have the specific diagnostic gear to read the 75's computers - and very few do.

This is a common problem with the 75s and, as earlier pointed out, is probably the connections under the front seat.

The simple cure is to cut off the connectors and solder the wires together. Have a look under the drivers seat and you will see two seperate pairs of yellow coloured cables each with connecting plugs (clipped on to chair frame). No need for an auto leccy if you can use a soldering iron. Disconnect the battery first though.

Most of the later 75s are OBD compliant so an OBD scanner would read some of the basic error codes. You do need a T4 to do any kind of detailed analysis.

Didn't Unkel have an airbag fault light problem on his 75 at some stage? I believe he resolved it farily cheaply.

Yup. Caused by frequent changing of the drivers seat position on the rail (both me and mrs unkel driving the car regularly). Unless it is just an easy loose connector under the seat, I would not touch it at all, let alone solder it :eek:

There are severe insurance and safety implications in tampering with your airbag system.

Went to (previous) main Rover dealer in Dublin and they diagnosed, replaced a connector and fixed the problem for €78 incl. VAT

If you disconnect the battery 30 minutes beforehand and use a gas soldering iron, then its completely safe.

Gas soldering is only for people who have plenty of experience. Normal electrical soldering is easy compared to gas tbh.

its not a connector. the seat moving back and forth has cut one of the wires on the left hand side towards the front. rejoin the cut wire(s) and all will be well.

I said use a gas soldering iron so as not to earth the wires. No real need but just a bit safer than an electrical one when working on airbags.

Gas soldering irons have a tendency to burn all around them if used in a confined space, unfortunately.

I also don't understand the logic of not using an electric iron on an airbag system. The house's electricity system is completely isolated from the car thanks to the tyres.

I guess a faulty iron could allow an electric charge to enter the system but in all reality, I would think that thinking about that sort of thing is a bit OTT.
I did read in a Mini/BMW technical document where the approved jointing method for under seat airbag systems repair was a specific crimped connection. This connection supported the wire much further from the actual connection & the theory is that with seat movements, this is less likely to break than a soldered joint which has a hard point when the wire meets the solder & becomes a weak point.

Thanks to all for the help. I had a look under the seats but might as well be looking into a field of thistles! Anyway I will go down the professional route and I wonder if Unkel could tell me the garage he used?
