My current one has the module 'cap' on it, temporarily attached with a pair of cable ties
Have already made up a nice lead, soldered / heatshrunk with the ex-module 4 pin plug one end and an eyelet the other.
A look at my tech data for a 106 and a 306 with Bosch pumps shows the following although I've purposely tried to ignore anti start modules, these are just solenoids as best as I can tell:
106f (old) Bosch 168061
106n (new) Bosch 166061 / 168095 / 168093 (increases with build codes)
306f (old) Bosch 19TD 1920z7 early
306f (old) Bosch 19TD 19200j (coded) probably keypad lump ?
306f (old) Bosch 19TD 1920w2 later standard ignition
306f (old) Bosch 18TD 168095 (not a UK model with the XUD7 as far as I know)
306n (new) Bosch 168061 / 168095 / 168093 (goes on build code)
Problem being, if I order one from the factors as I'm not going to the dealer for it due to excess cost, I can see it either having no thread in which case I won't take it or perhaps the throw will be wrong.
I'd rather not take mine out repeatedly if I can avoid it due to the difficult job of fitting ties around it and the pump head to hold it in place. Which reminds me I need to put a blob of threadlock onto two of the pump head bolts now I've replaced with suitable (tensile and the correct length) bolts.
