That doesn't sound good at all. I hope you didn't pay too much, if the motor's seized, repairing may be more than the car is worth.

If it's anything like mine, the upstream sensor is a 4-wire Denso. With VAT, the local dealer quoted £250 each to buy, extra to fit.

That model does not have a turbo.

If it were mine, I'd get it changed. The belts should be changed both on miles travelled or years age - yours exceeds the upper limit on age alone by some years. It is an interference engine so if the belt snaps or slips teeth, major repairs inevitably follow.

If it's a 2.5 4-pot, it's a belt. Chain only on the 3.0 6's.

Put my winter tyres - Hankook iCept Evo's - on.

Good to hear it's behaving itself.

Feedback. I removed the cowl panel and there was the speaker! Removed it, battled like !Removed! to open it, screws holding it together seriously rusted, eventually drilled them out, accessed the battery, tested 9v but amp test, poor compared to the new one I bought to install. Swopped over, closed up the speaker with silicon and cable ties (couldn't replace screws, my drilling had messed up the holes). Got a spook when the siren sounded full blast - tried the remote, no joy. Eventual[y realised the main car battery was still disconnected, re-connected that and all good. I've made 3 trips so far and all quiet. Hoping it stays that way.

Thanks a lot. I probably should'a looked there first. Friday I guess I know what I'm doing!

Mr B Me again and again with question about siren - how big are these? My reason for asking is I've just spent 3 hours taking the glove box, passenger side kick panel, centre console apart trying to find the siren without joy. All I found was a Sigma 30 black plastic box (control module I think) fastened to a frame attached to the blower motor. I tried tracing the leads marked siren but got lost when the wires disappeared into the dash further/into a loom).Is it possible the horn would be tucked below the cowl panel (plastic section across the car, below the widnscreen and in which the wiper motor/linkages sit?

Thanks guys, will have a search this weekend.

Mr B - any idea where the siren may be located? When mine beeps, sounds like it's coming from within the dashboard, centre, behind radio/climate control etc. I'd be grateful for a steer, thing's driving me crazy.

Mr B - how do I go about checking the pp3 battery or are they only replaceable by dealer/Sigma? I have random, single beeps which might be caused by this battery going flat.

I'm hoping the diagram loads OK, attached pdf. The diagram gives an idea of where the retainers (2 screws and 3 hook pawls) are located to get to the fog light switches. centre console picture.pdf

Are you sure they don't work? Some cars, the rear fogs wont come on unless the front fogs and/or headlights are on. If the switch has to come out, you'll have to remove half the centre console. The real tricky bit comes in getting to the 2 allen screws located hidden up within the ash tray area. Take the ashtray out completely, try and look up inside (behind the front panel, may need a mirror). There are 2 screws which need removing. After that, just clips around but also the connector for the ashtray light and the cigarette lighter need disconnecting.

I bought a Enduroline 005L from Tayna batteries in Feb; cost about £60 delivered to my door. Seems fine so far. Claims to carry a 4 year guarantee - remains to be seen. Had no problems with codes during/after changeover.

Me too!

The reason I ask about bearings is that some aftermarket bearings have communication problems with the wheel sensor/s, The bearing has a tone ring (magnetic ring) which a sensor on the hub reads as the bearing rotates and if the two don't correspond properly it confuses the cruise control computer. Its possible it'll also affect the ABS. Also, if the sensor on any wheel hub was damaged during fitting of replacement bearings, that'll result in faulty cruise.

Regarding the cruise control problem - has this just started, have you had the car for a while or just bought it? Has any work been done around any wheel (brake work, wheel bearing, cv boot etc) recently?

Either both wheels off the ground or both loaded (on ramps or similar). I wouldn't try changing drop links when one wheel per side is loaded.

Some folks use large hose clamps (aka jubilee clamps) round the loose heat shield/s and tighten - stops the rattle. Previous OB I had had about 6 of these round various heat shields. The squeal - are the belts you replaced tight enough/or too tight maybe? Whereabouts in Kent are you?

How/where do I get a pin from to place?

Title says 2007. Should be simple bolt on bearings.

Wheel bearings, front and rear on this series are a known source of potential problems. The only saving grace is they are easy to change.

Sounds like head gasket to me. Have you just bought the car or has this recently started? How's the oil?
