This is for car with relay 19, but it also fits a lot of other cars (Saab/Lotus/Vauxhall).

Taken from Lotus Forum:

Various part numbers have been put forward as replacements. Obtaining new relays is possible but the majority can be found from the local breakers yard:

* Beru: 0 900 301 082
* Kostal: 377 955 531
* Bosch: 0 986 335 058

MK3 Golf


One of the replacement relays known to work is from the MK3 Golf.

VW part no. 3B0955531 works, has 197 printed on top. Costs £28.83 new.

Going price from a breakers yard is around £5. Most breakers yards will have a number of Mk3 golfs, and the correct relay can also be found in lots of different VWs (usually the higher spec cars) dating from the mid '90s. In the golf, the relays (and fuses) are behind a plastic panel under the steering wheel, above the drivers footwell. You can just pull the relay out.

There are two common relays you'll find in the cars. The WRONG one has the number '19' printed on the top of it in big white numbers. This is really no different from the original lotus relay, and no upgrade at all. The CORRECT relay has the number '99' or '197' printed on it. This is what you need to find. The '99' or '197' relay is usually found in higher spec cars, and the '19' relay in lower spec cars.
