There are usually two (although some models have three) "electrovalves" on the bulkhead. These are variable solenoid valves that control the amount of vacuum to the EGR valve and turbo wastegate actuator. As far as I know the control signal to them isn't a straightforward dc voltage level. I have so...

You can see if the crank pulley has rubber inserts through the wheel arch. If you look at the edge of the pulley (facing the pulley retaining nut) you should see three arc shaped slots in the metal near the edge of the pulley, maybe 1/4" wide and a few inches long - the rubber part should be visible...

You have a solid crankshaft pulley? I thought the 2 piece one with rubber insert was standard on the 110 HDi. Could that be the source of the vibration? Has it always been a solid pulley?

You should take the opportunity to replace the rubber hangers and clamps. Motor factors sell a paste for helping the seal.

every 96K or 16 years according to dealer. I don't think these engines are known for cambelt trouble but the tensioners and idler pulleys can fall apart. Many people recommend changing the water pump at same time as the cambelt and if this wasn't done when your cambelt was changed the first time it ...

Whilst gingerly descending an icy hill yesterday in 1st gear (without touching the brakes) the ABS warning light on my 2003 406 came on. It was accompanied by a warning beep and message (that I didn't get the chance to read) on the multi function display. It did feel like the car slipped sideways a ...

I had the exact same problem on my 2003 406HDi after disconnecting the battery. The remote central locking refused to work and couldn't be re-initialised by any of the usual BSI reset / key re-teach procedures. A couple of local garages tried to do it and were also unsuccessful so I threw the towel ...

There are usually two solenoids on the bulkhead : one for turbo wastegate and one for EGR valve. Some models have a third one (something to do with brakes?). The turbo and EGR solenoids are the same so you can swap them to help you diagnose a fault. The HDi "manual" I have says something about the s...

This all sounds very familiar! Mine makes a faint whistling noise under the same conditions. Hardly noticeable until I tow the caravan and then its quite clear. I haven't found the problem yet but I presume it will gradually get worse and then be easier to find. I was thinking that under heavy load ...

Could possibly be air in the fuel system which has now purged through. Hopefully there isn't a problem with the seal on the housing which is allowing air to get sucked in (and a bit of diesel to leak out) As others have said before, many people recommend changing the whole fuel filter housing, not j...

I took my alternator off and took it to a local auto electrician who replaced the bearings - it only cost me £20. BUT, after about 14 months it started making a nasty noise again so I threw in the towel and got a Lucas remanufactured / exchange one from a local factor. So far so good...

Could be either, but... when my alternator bearings were shot there was a fairly loud whining noise when the engine was running. This disappeared when the engine was run without the aux drive belt. After removing the alternator from the car there was no obvious roughness or play on its pulley so I d...

On my 2003 406HDi Estate, any disconnection of the battery results in the keyfob not working. I have tried every procedure listed in the manual and on the internet to "re-programme" it and also various local garages have said they could do it "no problem" and then failed. Only a main dealer seems to...

On my D9 estate, there is a black metal spring clip just under the adjuster nut on the handbrake lever. If you try to slacken the adjuster nut whilst there is any tension at all on the cable, the aforementioned spring clip will disengage due to the inevitable twist in the threaded part of the cable ...

On my D9 estate, there is an adjustment possible on the main (central) cable where it connects to the handbrake lever. The cable terminates in a threaded rod with a nylon insert type nut on the end of it. Quite hard to access properly without removing the centre console.
