Hi there,

Any shortcut to determine glow plug unit brand other than removing the part.

Are these brands interchangeable? eg. beru unit with bosch glow plug and vice versa

www.realoem calls for exact match, guess has to do with pipe glow plug design or just a precaution measure.

Should diagnostic software help determining the brand, have Rheingold aka Ista-D.

Tx for your time and help
