Description

Complete voltage regulator. Suitable only for Bosch alternators.
Fits diesel T25s from 1981 to 1992, plus 1900cc and 2100cc petrol T25s from 1983 to 1992.
Also fits 1800cc to 2800cc VW T4s from 1990 to 1996.

This important component regulates the charging voltage produced by your vehicle’s alternator – maintaining it between 13.5v and 14.5v in order to run efficiently and to protect the electrical system. Too much voltage and costly damage could result with parts burned out; too little, and performance is weakened. It's well worth replacing if you are in any doubt as to its condition.

  • £4.15, brilliant

    First sign of this failing, was a very hot battery, ordered Monday, arrived Tuesday, fitted in 10min, working perfectly, no more fried battery.
    cheap as chips, probably cheaper.

  • poor quality

    I fitted this less than 18 months ago and it has now failed. There are better quality replacements available

    Thank you for your review, were sorry to hear you had a problem with this regulator we are not aware of any problems with these. Please can you return the unit to us so we can get it tested to see where the problem is Thanks JK
  • Excellent

    Battery light came on and I feared an expensive fix. A brief google later it looked like it was regulator that needed changed. Arrived in quick time and took 5 mins to change. I have zero mechanical skills but this was simple. Light off, T25 back to working order. Brilliant

    • I have just had my original bosch alternator reconditioned they have put a Cargo 135797 14v regulator on it, my T25 is a 1.6TD is this the correct regulator or should it be the one you are selling? Thanks

    • Hi - battery/generator warning light came on this morning. Belts all seem ok, so I'm hoping this may be the solution. Not sure if my alternator is Bosch - no logo on it. Is there any way to be sure? I have a 1986 Westfalia 1.6 TD. Cheers.
    • Answer: You would want to test the alternator or get someone to test it for you really to find what is at fault. tHANKS
