  I have a 2001 Opel Astra 1.7DTI which is suffering from a lack of power. I know this is not supposed to be lightening quick however I cant get it going even in the low gears. It is slow to pull away from junctions, go up hills, overtake etc. There is no ECU warning light appearing and every now

• Rover 75 air flow meter fitting 24 Jun 2006 (Forum)
  about fitting the meter. Is it a serious job for mechanics only??? Does the ECU error message on next service make a difference to the running of the engine?? Sorry if that sounded ignorant, I'm in over my head methinks.

• 1995 vw Golf Autobox probs 7 Jun 2005 (Forum)
  Hi all, I've got a 1995 1.8 Golf with 31k on the clock. The problem that I am having is that, sometimes during driving the gearbox 'hunts' through the gears causing the car to jump all around the place, which is quite scary! I had a diagnostics test done on the Auto ECU and it came back

• Subaru Impreza Import remapping 24 Jan 2004 (Forum)
  it should have its ECU remapped or face a melt down pushing to a std. 280bhp. Subaru UK don't touch them. The question is who is the best to approach from experience. He has a couple of names, so he's comparing your opinions. So who's the man??
• Catalysts on diesels 19 Dec 2003 (Forum)
  it and replacing it with a length of pipe cause it to fail the MOT on emissions or be illegal? (My friend's V-reg Saxo diesel doesn't have a cat fitted) Secondly, would removing the cat be detrimental to the performance/economy of the car. I've heard that it might confuse the ECU and give poor acceleration
• Renew Warranty? Or not? 21 Nov 2003 (Forum)
  ") on my '97 2.5. Steering ram? ECU? HP pump? But, there again, the definitions of "mechanical failure" made by Warranty Holdings are restricted to things actually breaking. Snapping, falling in half. So they may weasel out of any potential claim. So, to renew or not renew? Thoughts, anyone? rg
• Volvo 240 cat removal 15 Aug 2003 (Forum)

  and consistantly returns about 49 mpg. I am not concerned about this, but why does the light come on? Is the ecu making some adjustments? I have a tuning box fitted btw, which I guess could be to blame! Any general experiences of this? Thanks
• electronic ignition 7 Sep 2001 (Forum)
  Can any one clear up a query for me please? On a distributorless ignition system, my understanding is that a notch on the flywheel/crank or whatever, depending on the model, passes a sensor which sends a signal to the ECU, which in turn earths the coil circuit, and a spark is delivered to the plug

• Hyundai i20 - ABS Pump/Modulator 14 Jul 2017 (Forum)
  anyone know if it'll need coding (the garage didn't seem to be sure)? Also, I've seen ECU repairers who seem to be able to send repaired modules that don't need coding. So someone apart from Hyundai can get by the problem. Would be interested to hear from any Hyundai owner this happened
