Over the many years that we have been working on BMWs there are some problems that we have repeatedly encountered. We have highlighted a few of these below together with some tips we have found useful. If you have any tips of your own that you would be happy to have published on this page please submit them to us.

• Corrosion on early 3 Series BMWs (E21 and E30)
• Wet rear foot wells on 2-door 3 Series BMWs (E30)
• Leaking power sunroofs
• Poor running on big 6 L-Jetronic or Motronic engines
• Leaking fuel pressure regulators on injector rails
• Uneven response on accelerator pedal
• Replacing bulbs on the instrument cluster
• Overheating problems caused by faulty fan viscous coupling

Our technical sheets provide more in-depth information than our technical tips. We have published a couple of technical sheets here that we hope you will find useful. We will be adding to them and would be interested to hear from you about what you would like to see included.

Currently we have the following technical sheets:

• Cracked Head - a checklist of problems that can cause a cracked head through overheating.
• Replacing an ECU - hints and tips to ensure trouble-free operation.
• Diagnosing Overheating Problems - exactly what it says on the tin.
