I look after some 5 year old Linde gas IC counter balance's, H20 392 & H40 394 models.

Apart from routine service parts ( service kit including engine oil change every 1k hours ) the only bit's I've replaced due to failures since the trucks where new are:

1 x brake micro switch
1 x gas shut off valve
1 x handbrake lever operating rod
1 x catalytic converter
1 x inner rear wheel bearing
3 x coolant reservoir's

Linde have also upgraded & modified the gas shut of valve, coolant reservoir, catalytic converter & handbrake operating rod since my trucks where manufactured & the replacement parts haven't since failed.

I've never had any wiring issues. no distributor fitted either, German built, VAG group engines, easy to look after & a delight to operate.
