Thanks, Resistor is on order. I'll pop into the local garage on the way home from work to get the battery tested. I've also read there are sometimes issues with the suspension going up and down whilst parked. To try and eliminate this, I have put the suspension in the lowest position whilst parked at work.

I have just read the alarm has its own battery and these can go flat, which means a drain on the actual battery. Has anyone come across this?

Hi guys, I've had my HDi VTR since April this year and it's been fine up until a few weeks ago. I noticed that starting was a little lazy and after a few days of this of ignoring the problem, the battery was totally flat. I assumed the issue was an old battery and the constant use of the demist and short journeys had taken its toll on the old battery. I purchased a new battery two weeks ago and this morning it was lazy once again. I drive every day, but no more than 10 miles. The only other issue I've had, between the old battery going flat and today, the heater blower resistor has packed up (no heater). Could this be related? I'm dreading it being the alternator, are there any common faults with the C5 HDis? I've fitted nothing new to the vehicle and it doesn't have a tow bar.

Maf unplugged in the way to work this morning. No power what so ever, but when I eventually got to 70mph the mpg was showing 43 ish. So next step is to give the maf a bit of a clean and see if there's any improvement. I've read some mixed reviews about cheaper replacement mafs, so if I do get one it's going to coat over £100.

So after a bit more research, I'm going to investigate all four wheels properly and then take a look at the maf.

Egr cleaned using wynns egr cleaner and the result....... exactly the same as before. Is the egr valve at the rear of the engine?

Cheers random bloke. I've checked the brakes by feeling if the wheels had got hot, which they hadn't. I'm going to remove and clean the egr tomorrow. If there's improvement, I'll remove it all together at some point.

I also noted no change in power, but at idle when she was cold, was a little rougher.

I disconnected the egr via the blue connector this morning to see if there was an difference and it's practically the same. Approx 42 mpg at 70mph. I now have a suspicion the egr make not be closing properly or is stuck. I think I'll either buy one of these egr cleaning kits or remove it and clean it properly.

Hi guys. This is more noticeable when accelerating down a slip road etc. When changing gear there is a very slight whoosh sound. I've had other diesels and not heard this before. Does anyone know what it may be? Sorry if this is a newbie question.

It's the 110 bhp 2.0 engine. With the instant mpg showing, sat at 70 mph on a fairly flat road will show around 42 mpg. I've done a couple simple checks, such as tyre pressure and binding brakes. Could the egr be at fault? I'll plug my obd connecter in it tomorrow and see if there any logged faults.

I am a new owner of a 2004 C5 HDI VTR saloon. Around town I'm getting a display mpg of 39.2, which I am very happy with. However motorway driving at 70mph I'm getting 39.5 average. There's no noticable lack of power, no power surges and no displayed faults. Are there any known issues which I can do to increase the mpg? Or is there anything I can do to the display to get a more accurate reading?

I'm the new proud owner of a Citroen C5 hdi vtr. So far I am very impressed!
