Hi all. So quick question. I have a 2003 Jetta TDI. I know the timing belt change interval is 160,000km (100,000mi or so ), OR 5 years. My timing belt was completely redone in November of 2017 so the time interval is approaching, but I only have about 50,000km ( 31,000mi ) or so on the timing belt since then. So any recommendations on if I should be having it done again come the 5 year mark this November?? I have a slight noise from either the serpentine or timing belt not sure which. It's been like -40C here the last bit so maybe that's playing a role. At any rate I plan to have it looked at where I had the timing belt done in 2017. Just wondering any opinion on the low km but approaching 5 years and if I should just get it done as I'm sure that will be the recommendation. Thanks in advance!
