I see alot of truckers talking about electrical issues on these Volvo's, Does this include the 2004,2005 model years also? I'm wanting to buy a 2005 volvo but kinda hesitant now after seeing all the remarks.

Maybe that electrical display is having issues

The problems are with the D-13 Volvo Engine. I think the problem is with the EGR valve. The newer models have a recall on the cooling system and the computer's parameters. To be honest I see more Freightliners on the side of the road with the hood up than I see Volvos in a similar situation. In an 04 or 05 model I would go with the Cummins. I think they quit using Detroits in 03.

i worked for a company with Volvos, many had dash readout probs, minor stuff. They are well built trucks

The majority of electrical issues are caused by loose or dirty battery / ground (block, frame, starter, etc..) cables. CLEAN AND TIGHTEN YOUR BATTERY CABLES!!!! I can't stress this enough!

Iam also having problem with my 2005 Volvo VNL780, it all started with a flickering headlight then dashboard lights. Telltales started to show different fault problems then the radio, A/C, dashboard gauges is also getting crazy.I need help cummins volvo tech
thanks -
See post above yours. Sounds like you lost chassis ground or the hot. An 1/8 of a turn and some corrosion under the nut/bolt is enough. It started with the headlights flickering because it uses the most juice.
Check the hot at the starter by actually putting a wrench on it. In the dark, you might see sparks at the nut while cranking the starter if it's a hair loose.
The same with chassis grounds. Use a wrench, not your eyes. Follow off the battery to the frame. Then check the ground strap under the hood.
Last, check the hot at the jumper block under the hood. Then check the main hot at the fuse block.
Ignore the fault codes for the time being, because there are low voltage and high voltage faults that can be triggered from a bad connection.
After you have checked all the connections with no luck, then have diagnostics run on it. -
all Version-II, VN, FH, FM. But with d13a and D9B more problems
KB3MMX Thanks this.
