hey all newbie here. I have recently bought a 51 plate 307 2.0 hdi with 145k on the clock. it was very sluggish when i first had it but with advice from posts on here it seems to be better. my main problem is that over 3000rpm it has a major flat spot and seems to run out of power. i have changed the air oil and fuel filter and the oil and put some egr cleaner through it. has anyone got any thoughts on what might be the problem? i do intend to get it plugged in to see if anything comes up. another minor problem is that i have no side lights on the front and the horn and winscreen washers dont work. sorry about the essay but any help would be appreciated.

Disconnect the MAF sensor and see how it runs then. I've lost count of the number of 307s around the 110,000 - 140,000 mile range I've seen which has this.

It should be where the red arrow is.



Horn failure is also common, and the washer motor may need a jiggle. Its deep down behind the wheel arch liners.

If you can hear the motor running you may find the pipes blocked. Take them off and soak them in a bit of boiling water with a bit of bleach or limescale remover. Then thoroughly rinse. Then rinse again.

Hi,

I I had a power drop at 3k on my 2.0 Hdi just as yours. I gave it full service inc new air filter and that didn't fix it. After changing the MAF it was a lot better but still seemed to be down on power. I ran it for a short distance, about a mile without the air filter box lid attached so it was breathing air direct from the engine bay. It was like a new car, smooth and full power revving up to 4.5k clean.

Once it was back home I removed the air box assembly completely and about half a tree fell out of the feed duct from the wheel arch to the air box. I managed to turn the box partly over so I could see the under side of the winter heater matrix and it was clogged with straw and feathers. I used an air compressor to blow it all out and then re-assembled it all. Runs great every time.

Go with what Gibbo says though as MAF failure is common. Don't get a cheapo, as they don't work very well, you need a Valeo or Pug part.

Good luck,

PB

when i had this problem it was the turbo control electrovalve. it could either be he wiring to the valve has broken or the valve itself faulty. in my case i had both and since i fixed that it pulls amazing.

Any Planet owners near you?

If not, how "mid" is "Mid Wales"? I generally get out into Wales at weekends exploring abandoned mines and swimming in mountain lakes round Lake Vyrnwy way.

I think I've sorted it. I have cleaned the maf sensor with contact cleaner and cleaned the air intake. I also found a green plug was disconnected which the numpty at the garage I bought it off obviously didn't notice. Runs and pulls a lot better still a slight flat spot about 3000rpm but not nearly as bad as it was no change with the maf unplugged. Got a. P. Fault on but presume these have to be cleared. Many thanks to u all for ur advice. No doubt I,ll be back for more. Lol
